This
automotive "how-to" guide was specifically written to assist owners
of the 2007, 2008, 2009, and 2010 Ford Edge CUV in replacing the
brake/parking/signal, reverse and rear sidemarker light bulbs in the
tail light assembly.

The tail light
assembly of the 07-10 Ford Edge is held in place by two 8mm screws that are
located underneath the rear cargo door or "hatch". I found it easiest to
remove the two screws using an 8mm socket with extension bar on a ratcheting
wrench.

With the two 8mm
screws removed, you can pull the tail light off the rear of the car. There
are two metal spikes on the outer edge of the assembly that match up with
two black plastic holes on the body of the vehicle.

The first light
bulb at the top of the tail light assembly is the reverse or "back up"
light. It has a very light grey colored plastic base that can be removed by
rotating it 1/4 turn counter clockwise and pulling it straight out. Remove
the bulb from the socket by pulling it out. If it won't come out easily, try
wiggling it as you pull. Replace the old bulb with a new # 921 bulb. Insert
the bulb back into the tail light assembly and rotate it 1/4 turn clockwise
to secure it.

The bulb in the
middle of the tail light assembly is a dual filament bulb that functions as
the brake, parking and turn signal lights. It has a dark grey plastic base
that can be removed by twisting it 1/4 turn counter clockwise.

Pull out the old #
3157 bulb and replace it with a new one. (Sylvania lists the # 4157 bulb as
the correct replacement.) Insert the new bulb and socket back into the tail
light and twist it 1/4 turn clockwise to secure it.

The lowermost bulb
in the tail light assembly located close to the outer edge is the rear side
marker bulb. The small light bulb socket is a light grey color. Remove it by
rotating the base 1/4 turn counter clockwise and pulling it straight out of
the assembly.

To reattach the
tail light assembly, first line up the two metal spikes on the outer edge
with the two black holes on the body of the vehicle. Then push the tail
light flush against the rear of the vehicle and screw in the two 8mm screws.
Test the new bulbs by turning on the parking lights, the hazard lights, and
having someone step on the brakes and put the vehicle in reverse.
